Oak Ridge National Laboratory

In the race to build the world’s fastest supercomputer, researchers need the best tools they can find. That’s why developers at the Oak Ridge Leadership Computing Facility (OLCF) are working with Allinea DDT.

Situation

As researchers scale up their code to work on the colossal OLCF machines, traditional debugging methods, such as printfs, are too time-consuming to be feasible.

Solution

Allinea DDT, which can quickly find problems, even on code running on more than 200,000 cores.
